In THE PERFECT SMILE (Book #4), criminal profiler Jessie Hunt, 29, fresh from the FBI Academy, is assigned a disturbing new case: a woman in her 30s has been murdered after using a dating website for her affairs with married men. Had she gotten too close to one of the married men? Was she the victim of blackmail? Of a stalker? Or was there some far more nefarious motive at stake? The list of suspects takes Jessie into wealthy, manicured neighborhoods, behind the veil of seemingly perfect lives, lives which are actually rotten to the core. The killer, she realizes, must lie behind one of these fake, plastic smiles. Jessie must plumb the depths of his psychosis as she tries to both catch a killer and hold her own fragile psyche together—with her own murderous father on the loose, willing to stop at nothing until he kills her.
